Your journey in search of this cache will lead you to the vicinity of St George's Anglican church. It wont take you inside the church or even inside it's grounds but close enough to admire it from the exterior of the fencing that now surrounds it and which was erected in the last few years to prevent unsavoury goings on within its perimeter.
John Rex laid the foundation stone of this church in 1849 built on land donated by his father, George Rex, founder of Knysna. Construction commenced in 1850 based on a plan adapted by Sophy Gray, wife of the first Anglican Bishop of South Africa. The church was to be built then as the chancel of a larger church and when funds permitted, the nave etc. in the plan would be added. The church was consecrated in 1855. In 1919 the decision was taken to build a new church to the north.
This new church is the one you will most likely be viewing from GZ as it blocks the view of the smaller original church from this side.
